l SPECIFICATION forming part of Letters Patent No. 363,471, dated May24, 1887.

Application filed March 18,1887. Serial No. 231,454. (No model.)

To aZZ whom it may concern:

Be 1t known that I, J orrN LACHLER, a citizen of the United States,residing at Erie, in

the county of Erie-and State of Pennsylvania,

have invented certain new and useful Improve ments in Printers Quoins;and I do hereby declare the following tovbe a full, clear, and exactdescription ofthe invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the letters of reference markedthereon, forming part of this specification.

My invention relates to printers qnoins; and it consistsin the i mprovemen ts hereinafter set forth and explained.

My invention is illustrated in the accompanying drawings, in whichFigure 1 is a perspective view of a seclio of a printers chase andforni, showing my inif` proved quoin in place therein. Fig. 2 is a topor plan View of my improved quoin. Fig. 3 is a cross-section of the sameon the line x a: in Fig. 2.

Like letters refer to like parts in all the figures.

In constructing my improved quoin, I make the bottom A and one side, B,in asolid piece, preferably of malleable iron, cast with a studpin, D,on the bottom A, to receive the movable arm E, which constitutes theother side of the quoin. This arm Eis provided with au eye, e, in oneend,'adapted to lit on the stud-pin D. 'Ihe body of the arm E is alsoslightly curved at each end, so that when it is forced out against theside-stick F of a form one-half or more of the length` of the arm E isparallel with the other side, B, of the quoin.

Through the bottom A ofthe quoin I make an opening, a, in which I rivetthe stud b on 4o turned, as shown by the dotted` lines in Fig. 2,

which operation forces the arm E outward and tightens the quoin betweenthe chase and sidestick ofthe form, as shown in Fig. 1, in whichposition it remains until removed by turning the cam back.

Having thus fully described my invention, so as to enable others toconstruct and usethe same, what I claim as new, and desire to secure byLetters Patent ofthe United States, is"

l. The combination, in a printers quoin, ot' an arm hinged to the bodyof the quoin, and forming one side thereof, with a cam operating betweensaid hinged arm and the fixed side ofthe quoin, substantially as and forthe pn rpose set forth.

2. The combination, in a printers quoin, of the bottom A and fixed sideB with the hinged arm E and cam G, substantially as and for the purposeset forth.

In testimony whereof I ailix my signature in presence of two witnesses.

JOHN LAoHLER.
